Which two memory areas that are part of PGA are stored in SGA instead, for shared server connection?

You configure your database Instance to support shared server connections.
Which two memory areas that are part of PGA are stored in SGA instead, for shared server
connection?

A.
User session data

B.
Stack space

C.
Private SQL area

D.
Location of the runtime area for DML and DDL Statements

E.
Location of a part of the runtime area for SELECT statements

Explanation:
A: PGA itself is subdivided. The UGA (User Global Area) contains session state
information, including stuff like package-level variables, cursor state, etc. Note that, with shared
server, the UGA is in the SGA. It has to be, because shared server means that the session state
needs to be accessible to all server processes, as any one of them could be assigned a particular
session. However, with dedicated server (which likely what you’re using), the UGA is allocated in
the PGA.
C: The Location of a private SQL area depends on the type of connection established for a
session. If a session is connected through a dedicated server, private SQL areas are located in
the server process’ PGA. However, if a session is connected through a shared server, part of the
private SQL area is kept in the SGA.
Note:
* System global area (SGA)
The SGA is a group of shared memory structures, known as SGA components, that contain data
and control information for one Oracle Database instance. The SGA is shared by all server and
background processes. Examples of data stored in the SGA include cached data blocks and
shared SQL areas.
* Program global area (PGA)
A PGA is a memory region that contains data and control information for a server process. It is
nonshared memory created by Oracle Database when a server process is started. Access to the
PGA is exclusive to the server process. There is one PGA for each server process. Background

processes also allocate their own PGAs. The total memory used by all individual PGAs is known
as the total instance PGA memory, and the collection of individual PGAs is referred to as the total
instance PGA, or just instance PGA. You use database initialization parameters to set the size of
the instance PGA, not individual PGAs.
